Questions have swirled over how the mass rescues of foreign citizens would unfold, with Sudan’s main international airport closed and millions of people sheltering indoors. As battles between the Sudanese army led by Burhan and a rival powerful paramilitary group rage in and around Khartoum, including in residential areas, foreign countries have struggled to repatriate their citizens — some of whom are running short on food and basic supplies while hunkered down.

The Pentagon said earlier this week it was moving additional troops and equipment to a Naval base in the tiny Gulf of Aden nation of Djibouti to prepare for the evacuation of U.S. Embassy personnel. But the White House said Friday it had no plans for a government-coordinated evacuation of an estimated 16,000 American citizens trapped in Sudan.

Even as the warring sides said Friday they’d agreed to a cease-fire for the three-day Muslim holiday of Eid al-Fitr, explosions and gunfire rang out across Khartoum on Saturday. Two cease-fire attempts earlier this week also rapidly collapsed.

“People need to realize that the war has been continuous since day one. It has not stopped for one moment,” said Atiya Abdalla Atiya, secretary of the Sudanese Doctors’ Syndicate, which monitors casualties. The clashes have killed over 400 people so far, according to the World Health Organization.

The international airport near the center of the capital has come under heavy shelling as the paramilitary group, known as the Rapid Support Forces, or RSF, has tried to take control of the compound. In an apparent effort to oust the RSF fighters, the Sudanese army has pounded the airport with airstrikes, gutting at least one runway and leaving wrecked planes scattered on the tarmac. The full extent of damage at the airfield remains unclear.

Burhan said that some diplomats from Saudi Arabia had already been evacuated from Port Sudan, the country’s main seaport on the Red Sea, and airlifted back to the kingdom. He said that Jordan’s diplomats would soon be evacuated in the same way.

On Saturday, Saudi Arabia and Jordan both announced that they had started arranging for the repatriation of their citizens stuck in Sudan. Officials did not elaborate on how the plans would unfold. Jordan said it was “taking into account the security conditions on the ground” and was coordinating its efforts with Saudi Arabia and the United Arab Emirates.
